* No reported injuries or tsunami risk
(Updates with reports from mines, emergency office, previous
SANTIAGO, June 20 A 6.3 magnitude earthquake
struck copper-rich northern Chile on Monday, but there were no
reports of damage at major mines and authorities reported no
injuries or risk of tsunami.
State miner Codelco [CODEL.UL], the world's top copper
producer, said its Chuquicamata, Radomiro Tomic and Al Abra
mines were operating normally after the quake. Teck Resources
(TCKb.TO) also reported no impact at its Quebrada Blanca mine.
The U.S. Geological Survey said the earthquake struck 55
miles (88 km) northeast of Calama, at a depth of 69 miles (111
km), near the largest mines in Chile, which produces around a
third of the world's mined copper.
The navy said there was no tsunami warning after the quake
and the national emergency office said there was no reported
damage or injuries after the quake.
An 8.8 magnitude earthquake and tsunamis struck Chile's
central south in February 2010, ravaging local infrastructure
and industries but leaving mines in the far north untouched.
